Behavioral assessment tests for central hearing skills in individuals with sensorineural hearing loss: an integrative review

Abstract

Purpose: to identify the most used tests and the changed hearing skills in the central auditory processing of individuals with sensorineural hearing loss. Methods: an integrative literature review conducted between March and August 2021 in PubMed/MEDLINE, LILACS, SciELO, IBECS, and Index Psi Scientific Journals. The review included studies addressing central hearing skills with central auditory processing behavioral tests in subjects with mild to moderate sensorineural hearing loss. Two independent reviewers made the study selection, data extraction, and qualitative synthesis. The selection aimed at verifying whether the studies answered the research question. Literature Review: 39 studies were found for full-text reading; after applying the eligibility criteria, 13 studies were included in the review. Participants diagnosed with sensorineural hearing loss predominantly had hearing changes in verbal tests, in comparison with normal standards for individuals without hearing loss. Thus, the most changed skills are the ones that depend on speech sound discrimination. Conclusion: the Staggered Spondaic Word Test predominated among the most used behavioral tests, while the most researched central auditory skills were binaural integration and binaural separation.
